NameError: name 'tkFileDialog' is not defined
提问by evamvid
I'm trying to use Tkinter and get the user to choose a certain file. My code looks like this (I'm just starting out with Tkinter)
我正在尝试使用 Tkinter 并让用户选择某个文件。我的代码看起来像这样（我刚开始使用 Tkinter）
from Tkinter import *
from tkFileDialog import *
root = Tk()
root.wm_title("Pages to PDF")
root.wm_iconbitmap('icon.ico')
w = Label(root, text="Please choose a .pages file to convert.")
y = tkFileDialog.askopenfilename(parent=root)
y.pack()
w.pack()
root.mainloop()
When I run the program, I get an error that says:
当我运行程序时，我收到一条错误消息：
NameError: name 'tkFileDialog' is not defined
I've tried it with a few configurations I found online. None of them have worked; but this is the same basic error every time. How can I fix this?
我已经用我在网上找到的一些配置进行了尝试。他们都没有工作；但每次都是相同的基本错误。我怎样才能解决这个问题？

You are importing everything from tkFileDialogmodule, so you don't need to write a module-name prefixed tkFileDialog.askopenfilename(), just askopenfilename(), like:
您正在从tkFileDialog模块导入所有内容，因此您无需编写以 为前缀的模块名称tkFileDialog.askopenfilename()，只需askopenfilename()，例如：
from Tkinter import *
from tkFileDialog import *
root = Tk()
root.wm_title("Pages to PDF")
w = Label(root, text="Please choose a .pages file to convert.")
fileName = askopenfilename(parent=root)
w.pack()
root.mainloop()

Seems a space name problem. Try this:
似乎是空间名称问题。尝试这个：
try:
import Tkinter as tk
import tkFileDialog as fd
except:
import tkinter as tk
from tkinter import filedialog as fd
def NewFile():
print("New File!")
def OpenFile():
name = fd.askopenfilename()
print(name)
def About():
print("This is a simple example of a menu")
class myGUI:
def __init__(self, root):
self.root = root
self.canvas = tk.Canvas(self.root,
borderwidth=1,
relief="sunken")
self.canvas.pack( fill=tk.BOTH, expand=tk.YES)
self.menu = tk.Menu(self.root)
self.root.config(menu=self.menu)
self.helpmenu = tk.Menu(self.menu)
self.filemenu = tk.Menu( self.menu )
self.menu.add_cascade(label="File", menu=self.filemenu)
self.filemenu.add_command(label="New", command=NewFile)
self.filemenu.add_command(label="Open...", command=OpenFile)
self.filemenu.add_separator()
self.filemenu.add_command(label="Exit", command=root.destroy)
root = tk.Tk()
root.title('appName')
myGUI(root)
root.mainloop()
